In a titration, for an acid to neutralize a base, at the equivalence point, there should be an equal number of moles of H+ and OH-.
Moles of OH- can be found by multiplying the concentration of the base by the volume. (You will need to keep in mind the stoichimetric coefficients if the strong base is Ca(OH)₂, Ba(OH)₂, or Sr(OH)₂.
Moles of OH- = moles of H+
(0.253 M) * 0.005 L = 0.01000 L * c
c = 0.1265 M
The concentration of HBr is 0.127 M.
The reason why the reaction written on the picture can be classified as a synthesis reaction is :
the reaction shows one compound that formed from two compounds

Answer :
- Nuclear fission : In nuclear reaction, the nucleus of a larger atom breaks into two or more smaller nuclei. In fission process, protons and neutrons are produced and larger amount of energy is released.
Example : In nuclear power plant, the energy released from the process of nuclear fission which is converted into electrical energy that is used in our homes and factories.
- Nuclear fusion : In nuclear reaction, the nuclei of two or more smaller atoms combine together to form single larger molecule. In fusion process, the mass of the resulting nuclei is more as compared to the starting nuclei and large amount of energy is also released.
Example : This process occurs in the sun and stars. In this, the isotopes of Hydrogen, Tritium and Deuterium combine together to form a neutron and a helium atom under high pressure and temperature.
Answer:
1.06L = V₂
Explanation:
Charle's Law states that the volume of a gas is directly proportional to the absolute temperature when pressure remains constant.
The equation is:
V₁T₂ = V₂T₁
<em>Where V is volume and T absolute temperature of 1, initial state and 2, final state of the gas.</em>
V₁ = 1.83L
T₂ = -100°C + 273.15 = 173.15K
V₂ = ?
T₁ = 27°C + 273.15 = 300.15K
V₁T₂ = V₂T₁
1.83L*173.15K = V₂*300.15K
<h3>1.06L = V₂</h3>
For a neutral solution,
[H+][OH-] = 1 x 10⁻¹⁴
